FASTENER FOR MEETING-RAILS OF SASHES.

.EPECIPICATION forming part of Letters Patent No. 375,656, dated December 27, 1887.

Application filed June 13, 1887.

To aZZ whom it may concern.-

Be it known that I, JOHN H. SHAW, of New Haven, in the county of New Haven and State of Connecticut, have invented anew Improvement in Sash-Fasteners; and I do hereby declare the following, when taken in connection with accompanying drawings and theletters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in

Figure l, a top View of the fastener with the hook in the closed position and as about to be drawn inward; Fig. 2, a top View showing the hook as drawn inward against the keeper; Fig. 3, a top View of the base-plate; Fig. 4, a top view of the hook-disk; Fig. 5, an under side View of the handle-disk; Fig. 6, a vertical central section,the parts in the position as seen in Fig. 1; Fig. 7, a horizontal section across the upper face of the hookdisk; Fig. 8, a modification.

This invention relates to an improvement in sash-fasteners such as are adapted to be attached to the ineeting'rails of sashes, and which usually consist of a keeper on the bottom rail of the upper sash and a pivot-lever upon the top rail of the lower sash, adapted by rotation in a horizontal plane to engage the keeper on the upper sash, and so as to securely look the two sashes in their closed position; and particularly to that class of such fasteners in which the locking-lever is divided into two parts hung upon a pivot on the base, one part of ahook shape to engage the keeper and the other part to serve as a handle by which the hook portion may be turned into or out of engagement with the keeper, and to which second part an over motion is permitted, by which, after engagement has been made between the hook and keeper, a radial drawing movement will be imparted to the hook portion,and thereby draw the two sashes firmly together, and which drawing action is released by the return of the handle portion before it so engages the hook portion as to turn it from its closed position, the object being a simple and cheap construction of this class of fasteners.

A represents the base, which is adapted to Serial No. 241,193. (No model.)

be secured to the top of the upper rail of the lower sash. In the base a central post or pivot, B, is securely fixed as the axis upon which the locking-levers may turn. The base is constructed with a slot or groove, 0, of seg- 5 5 ment shape and concentric with the post B, and from this segment-shaped slot is a radial notch, D, the said notch being in line with the hook portion of the locking-lever when in its closed position. The locking-lever is com- 64 posed, first, of a disk, E, from which the hook F extends, this hook being of usual shape and adapted to engage a corresponding keeper, G, formed on a base, H, which is adapted to be secured to the bottom rail of the upper sash 65 in the usual manner. The disk E is constructed with an elongated central slot, I, in

a diametricalline with the hook F, as seen in Fig. 4, the width of the slot I corresponding to the diameter of the post B, and so as to ro- 7o tate upon the post in ahorizontal plane,yet be permitted certain radial movement.

In the upper surface of the disk E is an elongated recess, J, in one side of which is an inward projection, K. The sides of the recess J are parallel and equidistant from the center.

On the under side of the hook portion of the hook-disk isa downwardly-projecting stud, a, corresponding to and adapted to work in the slot 0 of the base. The second part of the locking-lever consists of a disk, L, having a concentric opening, M, throughit, and through which the post 13 extends. Upon the under side of the disk L, as seen in Figs. 5 and 6, is

a downward concentric projection, N, which in diameter corresponds substantially to the breadth of the recess J in the disk E, and so as to set therein, as seen in Fig. 6, the disk L serving to cover the recess and rest upon the upper surface of the disk E, as also seen in 0 Fig. 6. In the periphery of the projection N is a recess, 0, forming two shoulders, respectively, P and R. The extent of this recess should be about one-fourth the circumference of the projection N. The depth of the recess 9 5 is such as to permit the projection K to stand therein and allow the rotation of the disk L, and so that in turning the disk L either of the shoulders 13 B may be brought into rotative contact with the projection K, according to the direction in which the disk L is turned. The

disk L is provided with a radial extension, S,

to form a convenient handle by which the disk L may be rotated.

The hook-disk E is set upon the base, the disk L upon the disk E, as seen in Fig. 6, and the post B, introduced through the disk L, the disk E, and the base A and riveted, serves not only as the pivot upon which the parts may rotate, but also serves as the means for scour ing the three parts together.

The operation of the fastener is as follows: Suppose the fastener to stand in the open position, as indicated by broken lines, Fig. 1, and as seen in Fig. 7. The handle S and the hook then stand in the same line and parallel with the plane of the sash. At this time the shoulder It of the diskL is in contact with the projection K. The stud a of the hook portion of the lever stands at the extreme end of the slot in the base distant from the notch D. If, now, the handle be turned, as indicated in broken lines, Fig. 7, to bring the other shoulder, P, of the disk L into engagement with the other side of the projection K, then further turning or rotation of the disk L will cause the disk E and its hook to rotate therewith, and in such rotation the stud a on the hook-disk follows the concentric slot 0 until the hook arrives to the closed position, as seen in Fig. 1, which movement has brought the stud a into line with the inward radial recess or notch, D, and the end wall of the slot 0 stops the further rotation of the hook at that point. Fromthispoint, as seen in Fig. 1, the handle-disk L will turn independent of the hook-disk E, and because the shoulder P is now bearing upon the projection K to impart a. force to it in the direction of the radial notch D the result is that a radial movement is imparted to the hook-disk until the hook is drawn hard against the keeper, as indicated in Fig. 2, and so as to draw the two sashes together and hold them firmly.

To release the engagement of the fastener, the handle-disk is returned until the shoulder R comes into engagement with the stud K. Then, as the wall of the notch D prevents rotation of the hook-disk, it follows that an outward radial movement will be imparted to the hook-disk until the stud a has come into line with the concentric slot 0, which is when the hook has been projected from the keeper, as seen in Fig. 1. Then from that point the hook and handle disks will move together until brought to the fully-open position, as indicated in broken lines, Fig. 1.

In some cases it may be desirable to interlock the handle-disk and the hook-disk at either point. To do this the handle S may be hinged to the disk L, as seen in Fig. 8, and so as to swing in a vertical plane, as seen in broken lines in that figure, and the diskE provided with a corresponding notch, so that when the handle is in the lowered position it will engage the notch of the disk E, and thus couple the two disks together independent of their engagement by the shoulders P R and the projection K. I therefore do not wish to be understood as limiting the invention to having the handle made as an integral part of the disk L; but I make no claim in this applica tion for the divided handle, as that is embodied in another application, No. 240,404.

I claimin a sash-fastener, the combination of a base adapted for attachment to the one rail of the sash, the said base provided with a vertical pivot-post, B, and constructed with a slot, 0, concentric with said post, said slot having a radial notch, D, opening therefrom, the disk E, constructed with the engaging-hook F and with an elongated central opening, I, adapted to set over said post, the said disk E also constructed with a central elongated recess, J, concentrically in its upper surface, the said recess provided with an inward projection, K, and the handle-disk L,hung upon said post,adapted to swing in a horizontal plane, constructed with a downward projection forming shoulders P R, adapted to work in the recess J and against the said projection K, with a corresponding keeper adapted to be secured to the corresponding rail of the other sash, substantially as described.
